摘　　要：运用4种典型聚集度指标和Iwao方程考察测定3块水松样地的种群空间格局类型,并分析其格局形成原因;对不同取样尺度下的格局变化进行系统研究。结果表明,屏南水松种群空间分布大体呈聚集分布,且在25 m2取样单元上聚集密度较大。研究结果可为屏南水松天然林群落的保护和经营管理提供理论依据。The spatial distribution pattern of the population in Glyptostrobus pensilis natural community in Pingnan was determined using four aggregate indices Iwao＇s equation, and the causes of the evolved pattern were also determined. The results showed that the spatial distribution of G. pensilis presented an aggregating distribution with high aggregating intensity at the quadrat of 25 m^2. The results can offer theoretic guidance for G. pensilis population protection and management.
